8.If you've tried studying when you're tired,you know that it can seem very impossible to do well.A study of sleep in sparrows suggests the relationship between sleep and the ability to learn may be more complicated(复杂) than people knew.
Niels C•Rattenborg,a scientist from Wisconsin-Madison,wanted to find out how the sparrows were able to deal with getting so much less sleep.He and his team brought eight wild birds into a lab and watched them for one year.They invented a game to check how well the birds could learn.In the game,the sparrows had to peck(啄)three buttons (按钮)in a right order to get a food treat.The scientists discovered that the birds'ability to learn the right button order depended on(依靠)two things:the time of year and the amount of sleep the birds had had.
During the migration(迁徙)season,the sparrows were restless at night and got much less sleep than usual.Even so,they were able to understand how to get the food quickly as if they'd had a regular night of sleep.Outside the migration season,they found the sparrows that got less sleep than usual had much more difficulty learning how to get the food treats than birds that had a regular sleep.
The results show that the sparrows can deal with much less sleep during the migration season than usual.If scientists can find out why,they may learn from sparrows and find ways of helping people deal with getting much less sleep.Until scientists fully understand the relationship between sleep and learning,it's better to get plenty of sleep when preparing for an exam.

32.Why can sparrows get much less sleep during the migration season?D

C.They can get food quickly
D.Scientists still don't know the reason.
33.What fact does the passage lead you to believe?B
A.We should sleep as little as sparrows do.
B.We should get enough sleep before an exam.
C.When tired,we should try to focus on(聚焦) our study.
D.When tired,we should check how we can sleep less than usual.
分析 当你累了,如果还在努力学习,你很清楚做好这件事似乎是不太可能的.一项关于麻雀睡眠研究表明睡眠和学习能力之间的关系可能远比人们了解的更复杂.Niels C•Rattenborg,一位来自威斯康星麦迪逊大学的科学家,想找出麻雀是如何应对这么少的睡眠的.他和他的团队把8只野鸟放在实验室里,观察了它们一年.他们发明了一个游戏来检验这些鸟的学习能力有多好.在游戏中,麻雀为了得到食物,必须按正确顺序去啄三个按钮.科学家们发现鸟学习按钮正确顺序的能力取决于2个因素:一年中的时间和鸟类的睡眠量.在迁徙季节,麻雀夜晚不休息,所以睡眠比平常要更少些.即使如此,它们也知道如何快速获得食物,好像它们有一个正常的睡眠时间.在迁徙季节外,他们发现比平常睡眠少的麻雀在学习如何获取食物中比那些有正常睡眠的鸟会更困难.研究结果表明,与平常相比,麻雀在迁徙季节可以很好地应对较少的睡眠.如果科学家找出原因,他们可能会向麻雀学习,找到帮助人们如何应对睡眠少的方法.直到科学家们完全掌握了睡眠和学习能力两者之间的关系后,当准备一场考试时,我们就可以有充足的睡眠.
解答 31.B.主旨大意题.题干意为:文章主要是关于____.文章主要讲述了科学家通过研究发现麻雀在迁徙季节,即使没有充足的睡眠,也能快速获得食物,但在迁徙季节外,如果它们睡眠量少获取食物就会更困难一些,科学家希望向麻雀学习来找到帮助人们应对睡眠少的方法,故选择B.
32.D.细节理解题.题干意为:为什么在迁徙季节麻雀的睡眠更少一些?根据最后一段The results show that the sparrows can deal with much less sleep during the migration season than usual.If scientists can find out why,they may learn from sparrows…可知科学家发现了麻雀在迁徙季节可以应对较少的睡眠,但是他们还知道这其中的原因,故选择D.
33.B.推理判断题.细节理解题.题干意为:文章什么事实会让你相信?根据Until scientists fully understand the relationship between sleep and learning,it's better to get plenty of sleep when preparing for an exam.可知科学家只是发现了麻雀在迁徙季节可以很好地应对较少的睡眠,但是还未发现睡眠和学习两者之间的关系,所以在这之前考试前,我们还是有有充足的睡眠,故选择B.
点评 本文是一篇科普说明文,主要讲述了科学家通过研究发现麻雀在迁徙季节,即使没有充足的睡眠,也能快速获得食物,但在迁徙季节外,如果它们睡眠量少获取食物就会更困难一些,科学家希望向麻雀学习来找到帮助人们应对睡眠少的方法.对于科普一类的说明文,考生应认真阅读,理解文章大意,仔细审题,联系上下文在文中找到练习题相对应的答案或者依据.

Meng Meihui,14,from Dongying,Shandong,loved reading certain pieces of work.But she paid particular attention to her classmate's every composition,just to find her faults.

Luckily,Meng(78)A realized the problem.She stopped her silly behavior and focused on her own progress.
Wang Xiao,a psychology(心理学)teacher at Huangshi Foreign Language School,Hubei,agreed with Meng's practice.Wang said the best way to deal with jealousy is to turn it into motivation(动力)
"(79)Cthose who are better than you and focus on yourself,"Wang said."It's more important to improve yourself than to be better than others."
